Homework Statement



One can buy 1 Farad capacitors which are only a few centimeters long. Speculate
on how you can build such a capacitor. Assuming that you are using Strontium
Titanate as the dielectric find the minimum gap for a maximum voltage of 5 volts.
Find the effective area required to build such a capacitor. How can you put this area
into a volume that is only a few centimeters

Homework Equations


C=Q/V
C=EoA/d


The Attempt at a Solution


to find the minimum gap, i think we can start from dielectric strength??

You need to start by looking at the equation for the capacitance of a capacitor with a dielectric. The equation you listed is for capacitance with no dielectric.
